ABSTRACT:
A device for destroying hypodermic needles and syringes includes a housing in which a pair of fixed blades are secured at their bases and supported in parallel, spaced apart relationship. A rotating shaft extends through aligned holes in the apices of the blades, and a trio of cylindrical members, each having a cylindrical blade secured thereto, is assembled on the shaft with each cylindrical blade adjacent to a fixed triangular blade. The cylindrical members and cylindrical blades are each provided with a slot extending radially therein, all of the slots being generally aligned in the axial direction. A syringe is introduced through an opening in the housing to rest in the aligned slots of the blades and cylindrical members. The shaft is rotated to cause the slot edges of the cylindrical blades to rotate past the fixed triangular blades, thereby shearing the syringe and needle.
